GAS GENERATOR FOR LOCOMOTW'ES.

SPECIFICATION forming part of Letters Patent No. 383,395, dated May 22,18 88.

Application filed April 28, 1887. Serial No. 236,402. (No model.)

To all whom it may concern:

Be itknowu that I, ARTHUR O. HUIDEKOPER, of Meadville, in the county ofCrawford and State of Pennsylvania, have invented certain new and usefulImprovements in Gas-Genera tors for Locomotives; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification, inwhich Figure l is a vertical longitudinal section of a locomotive boilerand tender embodying my invention. Fig. 2 is a similar view show ing amodification of the same. Fig. 3 is a transverse vertical section takenthrough the tender.

My invention relates to certain novel improvements, which are designedfor practically utilizing what is known as fluid-fuel as a heating agentfor locomotive engines, which improvement will be fully understood fromthe following description, taken in connection with the annexeddrawings.

In the accompanying drawings, the letter A indicates the shell of aboiler of any approved construction; 13, the fines of the same, lead ingfrom thecombustion-chamber tothe smokeboX, and D the combustion-chamber.The lower part ofsaid combustion-chamber, in connection with the shellof the boiler, is formed with water-spaces or waterlegs E, surroundingthe combustion-chamber, as shown in Fig. 1 of the drawings, so as tosecure the full effective heat of the fuel in the generation of thesteam.

The letter F indicates a pipe leading into the upper part of the firebox or chamber V from a funnel, G, located outside of the furnace andarranged to receive liquid hydrocarbon from a suitable source of supply,the said source in the present instance consisting of a tank, H, locatedon the tender of the engine, and having a pipe extending therefrom overthe furnace, so as to supply the fluidfuel to the same, the pipe beingprovided with a stop-cock, h, by which the How of the fuel may beregulated.

From the upper part of the fire box or chamber extends a gooseneck pipe,K, into the combustion-chamber of the furnace, and into said goose-neckpipe extends one end of a pipe,

L, from the steam space or dome M of the boiler, whereby a forcible jetof steam may be injected into said goose-neck pipe, so as to carry overthe gases generated in the fire box or chamber when they are met byfresh air, causing rapid and intense combustion. Said pipe L hasstop-cock z in same to regulate supply of steam. The intensely-heatedproducts thus generated pass through the boiler-fines to thesrnoke'stack N, where they escape, as usual, parting on" their way withthe material portion of its effective heat to the water in the boilerfor the generation of steam therein.

In the modification shown in Fig. 2 of the drawings anordinarylocomotiveboiler is rep resented. To adapt my invention to thesame, I locate in the combustion-chamber thereof a fire-box, in whichthe gaseous fuel is generated. This fire-box is so constructed andarranged as to occupy the front portion of the combustion-chamber of thefurnace, and is preferably made of a metallic shell and lined withrefractory material, between which and the outer wall of thecombustion-chamber is left a space, It, open at the bottom and at thetop,'by means of which fresh air is supplied to the combustion-chamberto support combustion of the ignited gases therein. The heated productsof combustion pass through the boiler flues, as usual, and escapethrough the smokestack.

The letter S indicates two pipes which lead from the exhaust sides ofthe cylinders. These usually terminate in the Smokestack to form a draftin the same and through the furnace. In the present instance, however,the draft being produced by the injection at the rear of the furnace,the forward draft is unnecessary and the waste steam is utilized to heatthe feed-water to be supplied to the boiler. To accomplish this, thewaste steam is carried out by means of pipes T back to the tender, wherethe said pipes are coiled in the waterreservoir, so as to heat the watertherein pre viously to supplying it to the boiler. further utilize thewaste steam, it is discharged into the tank of the tender by means of apipe, U, leading from the coil. The water of con densation is alsoforced into the tender through the pipe.

Instead of the steam-blast induced through the pipe leading from thesteam-space of the boiler, the pipe may be provided with a valved branchleading from the air-brake reservoir of the engine, by means of whichablast of air may be introduced into the goose-neck pipe to force thegases and air into the combustion-chamber of the furnace and produce thenecessary draft through the same.

In both forms of the furnace the fire box or chamber at its lower endisprovided with a metallic skirt, V, which is preferably in the form of aninverted frustum of a cone, and at its lower edge is provided with arigid damper or valveJV, which may be operated by asuitable rod tocontrol admission of air from below, so as to regulate the combustion ofthe fuel.

The operation of my invention will be readily understood from the abovedescription without further explanation.

The oil tank may be located within the tender-reservoir,and this form ofconstruction will be preferable in most instances where the engine isused in very cold weather, as the heat from the tank will keep the oilwarm and in proper fluid condition.

It will be observed from the foregoing description of my invention,first, that I take the common steam directly from the head of the boilerand inject this steam into the bend of pipe K, so as to produce, byimpact of the steam against the outflowing gases of combustion, apositive draft into the combustionchamberfrom thefire-box. Thissiphon-shaped pipe K is directed downwardly for the purpose of producinga whirl of the heated gases and to effect a perfect combustion thereofin the chamber 1) before they pass through the boiler-flues B, and alsoto cause practically a uniformity of draft through all of said flues. Itwill also be observed that I utilize the exhaust-steam from the enginefor warming the feed-water in the tender, and also for keeping fluid theliquid-fuel in the tank H, which tank is provided with a cock locatedconveniently for enabling the engineer to regulate the supply of saidfuel.

I do not broadly claim under this application the feature set forth inmy preceding application, Serial No. 231,111, allowed March 30, 1887.

Having described my invention, what I claim,and desire to secure byLetters Patent of the United States, is-

1. The combination, with a tubular steamboiler having a combustionchamber, of a firebox, a flue leading out of the top of the firebox anddirected downward and forward in said chamber, and an injecting-pipeleading from the steam-space of the boiler into the bend of said fineand provided with a regulatingvalve, all constructed and arrangedsubstantially as and for the purpose described.

2. The combination, with a tubular steamboiler having acombustion-chamber, of a firebox located in said combustion-chamber, andhaving a downwardly-constructed extension, V, provided with a grate anda valve, a liquid hydrocarbon injector in said fire-box,a siphonshapedoutlet pipe or flue leading therefrom and into the combustion'chamber,and an injector leading from the steam-space of the boiler into saidsiphon-pipe, all constructed and arranged substantially as and for thepurpose described.

3. The combination ofatubularsteam-boiler having a combustion-chamber, afirebox located therein, a fiue-pipe connecting the said fire-box andcombustion-ohamber,and a steampipe leading from the boilerspaee to saidfluepipe, with a liquid-fuel reservoir provided with a valved deliveryspout, and a pipe adapted to receive the liquidfuel entering thefire-box and provided with a spray pipe or head located inside thefire-box, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

A. O. HUIDEKOPER.
